GPT-4 Turbo vs o1-pro
o1-pro leads GPT-4 Turbo on the Artificial Analysis Intelligence Index, 12.4 to 7.0, and GPT-4 Turbo costs 20.0x less per output token ($30.00 vs $600.00 per million). Updated October 21, 2026; 1 benchmarks have a result for both.
GPT-4 Turbo or o1-pro: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4 Turbo for output tokens 20.0x cheaper ($30.00 vs $600.00 per million) and work measured by AA Intelligence Index, where it leads.

Benchmark by benchmark
First the score: boards each model leads, per category, where both have a result. Then every board, a category to a fold; bars are each result on a 0 to 100 scale, so compare the two in a row, not one row with another.

What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
Chat turn
1K input + 500 output tokens
GPT-4 Turbo costs less
Repository review
50K input + 3K output tokens
GPT-4 Turbo costs less
Agent loop
200K input + 10K output tokens
GPT-4 Turbo costs less
Listed OpenRouter rates, without cache or batch discounts. A workload that does not fit a model's context window would need splitting.
